What are the types of galaxies?

Galaxies vary markedly in their size. The smallest galaxies are a few hundred light-years across and contain about 100,000 stars. The largest are up to 3million light-years across and contain more than 1 trillion stars. The estimated 100 billion galaxies that make up the Universe are separated by vast distances. Even those galaxies that belong to a relatively close grouping, or cluster, have huge, empty voids between them. The Large Magellanic Cloud (LMC), for example, is part of the Local Group along with our own galaxy, the Milky Way galaxy. The LMC is the galaxy nearest to our own, yet it lies 10,000 light-years away from us.
